<header>Max number of parallel deliveries to the same destination</header>

<center><tt>smtp_destination_concurrency_limit</tt></center>
<hr>

This parameter limits the number of parallel deliveries to the same destination
via the smtp delivery agent.

<p>

The default limit is the <a href=opt_default_destination_concurrency_limit>
<tt>default_destination_concurrency_limit</tt></a> parameter. It is probably
safer to limit the concurrency to 10.
